You know the season is in its twilight hours when you can recap not one, not two, but three roster moves all in the same day.

The Maple Leafs announced Wednesday that 2012 first round selection Morgan Rielly had been assigned to the Toronto Marlies. Rielly’s Moose Jaw Warriors failed to make the post-season, so the Leafs’ prospect’s season ended after registering 12 goals and 54 points in 60 games. Pretty darn impressive, huh. Rielly is expected to wear #44 for the Marlies.

Jon Abbott spoke with the first-time pro earlier today:

Now, I don’t think it was the biggest surprise – but in the second piece of roster news; smooth skating defenceman Jake Gardiner had been assigned to the Maple Leafs and is expected to join the big club Wednesday against Tampa. In exchange for Gardiner, the Marlies were gifted Korbinian Holzer. I probably don’t have to tell you, but Holzer held down the blueline during the Marlies run to the Calder Cup Finals last spring.

If you need a refresher, here’s 20 Questions with Holzer:

Now to close out the day, the Toronto AHL club released that Mark Owuya had been assigned to the ECHL Royals. There was a bit of a logjam in net following the signing of Drew MacIntyre. Owuya appeared in 10 games for the Marlies this season, where he collected four victories. The Royals currently sit first in their division and have clinched a playoff spot.

Last summer, Marlies general manager Dave Poulin had this to say about Mark Owuya.
